javascript - 将对象数组的值拼接成一个句子

Question

我有一个 api 响应，如下所示:

"payload": {
    "paragraph": {
        "id": 2692,
        "words": [
            {
                "id": 21679,
                "position": 2,
                "translation": {
                    "text": "something",
                    "language_name": "english"
                },
                "transliteration": {
                    "text": "another",
                    "language_name": "english"
                }
            },
            {
                "id": 21671,
                "position": 1,
                "translation": {
                    "text": "Then",
                    "language_name": "english"
                },
                "transliteration": {
                    "text": "fa",
                    "language_name": "english"
                }
            },
            ...
        ]
    }
}

如何从 translation 造句 key 基于 position key 。例如，预期的输出应该是一个对象，如: {line: "Then something"}

Answer 1

首先你需要对你的positions进行排序然后你可以使用 map 加入他们，如下所示。

let words = [
    {
        "id": 21679,
        "position": 2,
        "translation": {
            "text": "something",
            "language_name": "english"
        },
        "transliteration": {
            "text": "another",
            "language_name": "english"
        }
    },
    {
        "id": 21671,
        "position": 1,
        "translation": {
            "text": "Then",
            "language_name": "english"
        },
        "transliteration": {
            "text": "fa",
            "language_name": "english"
        }
    }
]

let word = words
       .sort((a, b) => a.position - b.position)
       .reduce((word, w) => `${word} ${w.translation.text}`, "");

console.log(word)
